    \brief Container for context-sensitive controls.

    ToolBar is a container of application-wide and context sensitive
    actions and controls, such as navigation buttons and search fields.
    ToolBar is commonly used as a \l {ApplicationWindow::header}{header}
    or a \l {ApplicationWindow::footer}{footer} of an \l ApplicationWindow.

    ToolBar does not provide a layout of its own, but requires you to
    position its contents, for instance by creating a \l RowLayout. If only
    a single item is used within the ToolBar, it will resize to fit the
    implicit size of its contained item. This makes it particularly suitable
    for use together with layouts.
